The government's crackdown on aggressive tax avoidance schemes is the subject of a lot of press attention. Most of the reporting centres on the high profile individuals who enter into these schemes. 

A point that sometimes gets overlooked is that a lot of the individuals entering into these schemes are often very poorly advised (if they are advised at all) and those that promote these schemes can take advantage of that, and so it is interesting to read that many of those individuals are now joining together to litigate against the scheme promoters.
